4 Claims.

The present inventionrelates to winding machines, as for instance forthreads, and particuv larly to the traverse feed means employed in suchmachines. I I

An object of this invention to provide a novel I and improvedconstruction for the traverse feed means of winding machines, wherebyadjustments are easily made to change the length of stroke of such feed,to accommodate spools of different lengths.

A further object hereof is to provide a novel and improved adjustabletraverse feed means of the character mentioned, whichis of simpleconstruction, cheap to manufacture, easyv touse and eflicient incarrying out the purposes for which it is designed.

Other objects and advantages will become apparent as this disclosureproceeds.

In the acompanying drawings forming part of this specification, similarcharacters of reference indicate corresponding parts in all the views.

Fig. 1 is a front elevation of an embodiment of this invention.Included, is a double acting cylinder whose piston, having areciprocatory movement, serves as the traverse feed arm, for supportingand conveying the thread. The mechanism is here shown in its conditionwhen the piston is at one end of its stroke or travel. Means areincluded for adjustment of such stroke.

Fig. 2 is a fragmentary view of Fig. 1, showing the condition of themechanism when the piston is at the other end of its travel.

Fig. 3 is a fragmentary section taken at line 33 in Fig. 1, showing africtional device used in this embodiment.

Fig. 4 is a wiring diagramof an electrical circuit employed in thisembodiment.

In the drawings, on a frame I5, is mounted a double acting cylinder I6,controlled by a solenoid valve ll. This valve is in circuit with a microswitch l8, and a source of electrical current IS. The cylinder I5, maybe actuated, meaning its piston moved, by either oil, water, air orsteam.

The numerals 28 and 2| indicate pipes connecting the valve means [1 withthe respective ends of the cylinder. The numeral 22 designates thepiston rod. The apparatus set forth in this paragraph, needs no furtherexplanation as to construction and operation, as same is well known.

A screw 23, has reduced unthreaded ends 24 and 25, at which ends it issuspended and slidably mounted through a frame bracket 25 and a device21, respectively. Said screw 23, is positioned spaced from and parallelto the piston 22. This screw carries a pair of members 28 and 29thereon,

33, carries a member 35 secured thereto.

which really are comparative large nuts associated respectively withindependently moveable small lock nuts 38 and 3| therefor. All said nutsare in threaded engagement with said screw 23. It is evident that therespective positions of the members 28 and 29, along said screw, aremanually adjustable.

- One end of the piston rod '22 is interiorly threaded as a nut alongthe line of its axis to receive a screw 33. The amount of extension ofthe screw'33 forward of said end of the piston rod 22,

is of course adjustable and its position maintained by a lock nut 34.The forward'end of said screw Said members, are preferably hubbed discs,of a size that the disc portion of member35 travels between and cancontact the other of said discs of the members 28 and 29, respectively.

The micro switch I 8, is of the push-button type, and is positioned onthe frame'whereby its push button l8, may be contacted and moved by anend of the screw member 23. The device 21, is intended to hold the screwmember 23 in frictional engagement against longitudinal movement by thespring 36 when stressed, but yet, permit such longitudinal'movement ofsaid screw member 23, when caused by movement of the piston 22. Saiddevice 21, includes a pair of blocks 31,- having opposite concavechannels through which screw end 25 lies and slides. Adjustment of thescrews 38, against springs 39, will determine the frictional grip onsaid screw member 23, meaning on the latters end portion 25. The otherend of the piston 22, may have the bar 40 extending laterally therefrom,which bar carries a suitable thread eye 4|, for guiding the thread 42along the spool 43, on rotary spindle 44.

To set the apparatus, piston 22 is set to a position for guiding thethread 42 onto and at end A of the spool #3. Screw 23 is manuallyshifted to push button l8 to a position where the switch I 8 is inclosed condition. Members 35 and 28 are brought in contact, and locknuts 38 and 34 tightened. Piston 22 is now moved to a position forguiding the thread onto and at end B of the spool 43. Screw 23 ismanually shifted so that push button moves outward and switch it! is inopen condition. Member 29 is now brought into contact with member 35,and lock nut 3| tightened. Screws 38 are adjusted. The cylinder 16 isnow operated, and discrepancies noted. Adjustment thereof is then madeby slight change of position of the members 28, 29 and 35, until trathespool 43, is proper.

the member 35 will have contacted member=29;-

as shown in Fig. 2, and switch [8 will be open, causing valve means todirect'operatingmedium to cylinder it through pipe 21, arid pistonwillreturn to its position as in Fig.1;rwhenthecyclea repeats.

This invention is capable of numerous-- forms and various applicationswithout departing from the essential features herein disclosed. 11. istherefore intended and desired and that the spe- -cific embodimentherein shall-be deemed illustrative and n-ot'restrictive and that thepa-tent shall cover all patentable' novelty herein set forth; referencebeing had to the following claims rather than to the specificdescriptionherein to indicate the scope of this invention.
